Abaqus CAE vs ANSYS：优势对比分析

最好的软件是你知道如何很好地使用并适合你的预算。ABAQUS的许可已经改为扩展的Tolkens，这比ANSYS要便宜得多。另外，ANSYS依靠与DYNA的合作进行显式分析 ，而ABAQUS则将其全部集成。你可以在分析步骤之间从显式/隐式切换。ANSYS WB对初学者来说比较容易，但很难得到一个真正好的网格。在任何情况下，你必须使用一个更专业的网格器（如Hypermesh或ANSA）。就行业而言，ABAQUS在汽车行业的渗透率 更高，而ANSYS在能源行业更受欢迎。ANSYS的APDL界面已经过时了20年（ABAQUS CAE要好得多，也更直观）。虽然ANSYS的参数化设计 语言仍然有用，但你可以用Python和ABAQUS得到同样的结果。ANSYS不提供与RST的接口的API。因此，如果你正在开发一个依赖于读取ANSYS结果（file.rst）的应用程序，这可能是一个痛苦。ABAQUS提供了一个非常好的API，所以你不需要担心数据库结构 的细节问题。据我所知，人们更喜欢在ABAQUS中开发UMATs，而不是ANSYS。我对一个好的选择的提示是：看一下整个家族。在产品开发过程中还有什么可以支持你？你是否需要光学 、疲劳、多体、CFD、显式、声学、电磁学 等？ANSYS带有CFX、FLUENT等。但你必须为所有这些单独付费。ABAQUS带有TOSCA、fe-safe 、Simpack、xFlow、xFEM，你不需要为它们全部付费。你买的是tolkens。取决于你买了多少tolkens，你可能可以同时使用其中的几个。值得一提的是，在航空航天 领域，NASTRAN仍然是参考。而在学术界，COMSOL正得到越来越多的认可。

The best software is the one you know how to use well and fits in your budget. ABAQUS licensing has changed to extended tolkens which is way cheaper than ANSYS. Also, ANSYS relies on the partnership with DYNA for explicit analysis whereas ABAQUS has it all integrated. You can switch from explicit/implicit between analysis steps. ANSYS WB is easier for the beginners, however difficult to get a really good meshes . In any case you'd have to use a more professional mesher (as Hypermesh or ANSA). In terms of industries, ABAQUS has greater penetration in the Automotive while ANSYS is preferred in the Energy Industry. ANSYS APDL interface is outdated by 20 years (ABAQUS CAE is way better and more intuitive). The ANSYS Parametric Design Language is still useful though, but you can get the same results using Python with ABAQUS. ANSYS doesn't offer an API to interface with the RST. So you if you're developing an application that depends on reading ANSYS results (file.rst) that could be a pain. ABAQUS offers a very good API, so you don't need to worry about the details on how the database is structured. People prefer to develop UMATs in ABAQUS rather than ANSYS as far as I am aware. My hint for a good choice: Have a look at the whole family. What else is there to support you along the product development? Will you need optmization, fatigue, multi-body, CFD, explicit, acoustics, electromagnetics, etc.? ANSYS comes with CFX, FLUENT, etc. But you have to pay for all of them separately of course. ABAQUS comes with TOSCA, fe-safe, Simpack, xFlow, xFEM and you don't need to pay for all of them. You buy tolkens. Depending on how many tolkens you bought you may be able to use few of them simultaneously. It is worth mentioning that in aerospace NASTRAN is still the reference. And in Academia COMSOL is getting increasing acceptance.
